WILLIAM E. WOODS, OF GRIFFIN, INDIANA.

WAGON-BRAKE.

Application filed September 16, 1909.

T 0 all whom it may concern:

Be it known that I, WVILLIAM E. lVoons, a citizen of the United States, residing at Griflin, in the county of Posey and State of Indiana, have invented certain new and useful Improvements in \Vagon-Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a wagon brake and is especially designed as an improvement over my wagon brake construction shown in Patent No. 913,342.

The primary obj eet of this invention is the construction of a wagon brake arranged to be automatically applied by a backward movement of the draft animals against the wagon tongue.

A further object of the invention is to provide manually operated means for applying the brake so that the draft animals may be allowed to'rest from time to time when going down a steep hill or decline.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangementof parts as will be more fully described and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my improved wagon brake; and Fig. 2 is a plan view thereof. Fig. 3 is a transverse section taken through the wagon in front of the rear wheels and brake shoes, looking rear-wardly. Fig. 1 is a detail perspective view of the running gear of the vehicle with my improved brake applied thereto.

Referring to the drawings for a more particular description of the invention, 1 and 2 denote the rear and front axles respectively, which are of the usual type and 3 the reach bar which extends between the axles and is connected thereto in any desired manner. plurality of braces 4 and 5, may extend forwardly from the rear axle and are connected by means of a strap or securing plate 6, to the reach bar 3. At the point where the braces 4 and 5 are connected to the reach bar 3, a plurality of bars 7 and 8 are secured on opposite sides of said reach bar against the ends of said braces so as to form spaces 9 across which the brake shoes 10 and 11 are arranged to move. Said brake shoes are piv- Specification of Letters Patent.

oted by means of pins 12 and 13, at points intermediate their ends to the ends of the cross bars 7 and 8 and are connected at their inner ends to link straps 1 1 and 15, which extend forwardly in a horizontal plane and substantially parallel with the reach bar. The straps 14 and 15 are pivotally connected with the operating levers 16 and 17, on the outer ends of said levers and said levers are pivotally mounted between their ends on a cross bar 18, which extends across the reach bar 3 and is connected to the underside thereof. The inner ends of the levers 16 and 17 are connected to the ends of a U-shaped operating member 19, which slides through and is guided in its movement by a U-shaped bearing 20, the cross-piece or central portion 21 of which is disposed beneath the reach bar. The forward end of the operating member 19, works in a recess 22, in the front axle and between the front axle and the front bolster 23.

he tongue 25 is provided with an enlarged inner end provided with a horizontal longitudinal slot 26, through which passes a guide bolt 27. By this construction, when descending a hill or decline, the draft animals by pulling back on the tongue bring the inner end thereof against the front end of the operating member 19, which is caused to slide rear-wardly and apply the brake shoes 10 and 11. The tongue is also provided with a perpendicular slot 26, so that it may be used in connection with a stiff tongued wagon wherein no provision is made for Vertical swinging movement of the tongue. Under these conditions, the slot 26, receives the vertical bolt which connects the tongue with the hounds of the wagon.

I will now describe the means employed whereby the brake shoes may be applied manually so that the draft animals may be allowed to rest from time to time in descending a hill.

A segmental rack 28, is suitably supported by means of the laterally extending supporting bars 29, at one side of the vehicle and is provided with a central bearing recess 30, in which and in bearing recesses formed in the vertical pieces of the bearing 20, is mounted a transverse rock shaft 32. An operating lever is arranged at the outer end of the rock shaft and is provided with a spring actuated pawl or click 34, which is adapted to engage the notches of the rack. A cord 35, or other flexible element is attached at one end to the front end of the the front and rear portions of the operating sliding member 19 and is then partly passed member and a pawl and rack for holding the around the rock shaft 32. The cord is then operating lever in adjusted position.
